In my limited experience, the Oracle version is a lot more difficult to use than SSTA. (I think) it requires setting up a sampling of a particular query or table, through Grid, and then analysing the results offline. I love the "missing index" feature of the explain plan in SSMS also - and missed it heavily when I moved to a shop that does Oracle.
